CAMRT Radiography Practice Exam

When x-raying a supracondylar fracture, which part should be in contact with the image receptor?

1. The elbow

2. The wrist

3. The humerus

4. The forearm

The correct answer is: The humerus

When x-raying a supracondylar fracture, it is essential for the humerus to be in contact with the image receptor. This positioning is crucial because the fracture typically occurs just above the elbow joint, involving the distal humerus. Proper alignment ensures that the area of interest is captured accurately, providing clear images of the fracture line, which is vital for diagnosis and treatment planning. By positioning the humerus against the image receptor, radiologists can minimize distortion and superimposition of surrounding structures, allowing for a better assessment of the injury. This technique also facilitates an appropriate exposure, optimizing image quality while reducing the risk of unnecessary radiation exposure to other areas.
